There are some very good things about open education. This way of teaching allows the students to grow as people, and to develop their own interests in many subjects. Open education allows students to be responsible for their own education, as they are responsible for what they do in life. Some students do badly in a traditional classroom. The open classroom may allow them to enjoy learning. Some students will be happier in an open education school. They will not have to worry about grades or rules. For students who worry about these things a lot, it is a good idea to be in an open classroom.

    But many students will not do well in an open classroom. For some students, there are too few rules. These students will do little in school. They will not make good use of open education. Because open education is so different from traditional education, these students may have a problem getting used to making so many choices. For many students it is important to have some rules in the classroom. They worry about the rules even when there are no rules. Even a few rules will help this kind of students. The last point about open education is that some traditional teachers do not like it. Many teachers do not believe in open education. Teachers who want to have an open classroom may have many problems at their schools.

    You now know what open education is. Some of its good points and bad points have been explained. You may have your own opinion about open education. The writer thinks that open education is a good idea, but only in theory. In actual fact, it may not work very well in a real class or school. The writer believes that most students, but of course not all students, want some structure in their classes. They want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.

    Some people may think I'm crazy when I say “work is rest”. But that's the way it is — we need to rest. Without rest, we will die. At a minimum, we won't have the energy to work.

    Nobody forces us to be so stupid about this. We just don't know how to rest properly. We rest in ways that are not restful, even stressful. Some of our ways of rest interfere with our working energy. Instead of sleep, we go to the movies and clubs, drink or have a smoke with friends. This is because we misunderstand the meaning of “rest”.

    We should remember that rest means not working, both physically and mentally. Only then is it real rest. When tired, rest. It's simple. Actually, dogs and cats are smarter about this than people. People are stupid enough to rest in ways that destroy their capacity to work.

    Rest and work always go together. There must be a balance: work during the day and rest at night. When the sun comes up, one has plenty of strength to work well and enjoy it. In other words, rest is a kind of investment, so that one has the strength and energy to continue working. So we need rest to work, recognizing that we can't have one without the other. Rest is what recharges our batteries. We need enough time to charge up adequately to the tasks we undertake. Thus, we need to rest correctly; otherwise, illness will occur and also can affect the efficiency of our work.

    Rest can't be skimped. Without enough rest, good work is impossible. This is why we say that rest is another kind of work.

    Here's an interesting fact: Every teenager American seems to have, at some point, appeared drunk or rude online. This generation didn't invent stupidity, of course; it's just the first to post the picture online the entire world to see. And that's the rub: Employers are getting clever at looking you up online. They look at what people post and wonder. Is that new salesperson, the one who made a strange face on collegehumor.com,likely to do the same at a conference?”

    Anything that you put online is public information. This should seem pretty obvious to the generation who grew up on these sites, right? But it's not. When it comes to the Net, young people tend to fell for two traps. One:“ Many of them believe it's truly private, and they'll determine who gets to sec what, and it will stop there.” Wrong! And two: “Their sense of what things will be like in the next stage of their life is not realistic.”

    So what do you do about that picture? Take it down! But what if it is now on other sites? After all, a friend can post your photo elsewhere, and from there, it can be posted on another site. This problem is so common that a new industry has appeared: identity management, which helps people remove embarrassing material.

    The new industry serves to remind us that we've got to be careful out there. Most of us have got drunk or done something we regret. But putting it online is another matter. And for some, it's even become an addiction, one with a nickname: Crackspace. Young or old, students and managers alike turn into exhibitions, putting every aspect of their lives on public display(展示).

    Yes, it can be great fun. But should those of us posting pictures of ourselves dancing in our underwear be given a good comment? In a forgiving, kindly environment, yes. But what about in a business environment? Well, you decide.

    Street art is a very popular form of art that is spreading quickly all over the world. You can find it on building, sidewalks, street sings and trash cans from Tokyo to Paris, and from Moscow to Cape Town. Street art has become a global culture and even art museums and galleries are collecting the works of street artists. Even advertising companies also use street art in their ads due to its popularity.

    Street art started out very secretly because it's illegal to paint on public and private property without permission. People often have different opinions about street art. Some people think it is a crime with others think it's a new form of culture.

    Art experts claim that the movement began in New York in the 1960s. Young adults sprayed words and images on walls and trains. This colorful and energetic style of writing became known as graffiti(涂鸦). Graffiti art showed that young people wanted to rebel against society. They didn't want to accept rules, and they travelled around cities to create paintings that everyone could see. In many cases, they had trouble with the police and the local government.

    Many street corners in Paris show the works of Space Invader. A French artist uses small pieces of glass to make images of space creatures. He has been doing this for some years and the police have arrested him a few times. On his website, you can see many other places where he has created this form of art.

    Street artists do their work for some reasons. Some of them do not like the artists who make so much money in galleries and museums. They choose street art because it is closer to common people. Some artists try to express their political opinion in their works. They often want to protest against big firms and corporations. Others like to do things that are forbidden and hope they don't get caught.

    In today's world, the Internet has a big influence on street art. Artists can show their pictures to people all over the world. Many city residents, however, say that seeing a picture on the Internet is never as good as seeing it alive. The street art movement lives with the energy and life of a big city. There it will continue to change and grow.

    Learning is so complex that there are many different psychological theories to explain how people learn. A psychologist named Albert Bandura suggested a social learning theory which shows that observation, imitation (模仿), and modeling play a primary role in this process.

    In Albert Bandura's opinion, people can learn through observation. Observational learning doesn't even necessarily require watching another person join in an activity. We can also learn by reading, hearing, or watching the actions of characters in books and films. However, just observing someone else's actions isn't always enough to lead to learning. Your own mental state also plays an important role in determining whether a behavior is learned or not. In addition, though in many cases, learning can be seen immediately when the new behavior is displayed, yet sometimes we can learn things even though that learning might not be immediately obvious, which means people can learn new information without showing new behaviors.

    Not all observed behaviors are effectively learned. Certain requirements need to be related to the observational learning process. For example, you need to be paying attention. Also your retention is an important part of observational learning as you need to pull up information later and act on it during the process. Once you've paid attention to the model and kept the information, it's time to actually perform the behavior you observed. Further practice of the learned behavior leads to improvement. Finally, you have to be motivated to imitate the behavior that has been modeled.

    Social learning theory have many real-world applications. For example, researchers employ it to look into and understand ways that positive role models can be used to encourage desirable behaviors. Besides, it's also applied in the field of education, and today, both teachers and parents recognize how important it is to model appropriate behaviors.

Reading a book and watching a film are two very different experiences, but expectations can be high when a film of a favourite book is made. There are very many times I have been disappointed by a film of a book I love. So maybe highly regarded books do not always make good films. It is safe to say that great movies may be made from not particularly good books.

The source material may be anything from classic novels, short stones, comic books and stage plays, as well as non­fiction such as biography and autobiography, even those written by ghostwriters. All can work well, but why do many adaptations and indeed remakes fail with both cinema audiences and critics?

A key question is obviously how close to the original the film is. Since a typical film is only around two hours long, it becomes a question of what to leave out, and how to script the dialogue. Sometimes there may be changes to the plot, additions and even different endings to please producers, directors and test audiences. I, like many people, have often left the cinema feeling "the film is not like the book".

Another problem area is the cast. Whether suitable actors are found or not can mean the difference between success and failure. Readers of the book use their imaginations to visualize characters and have very definite ideas about how characters look and sound. This is where I think many film adaptations fall down.

Some books are just too difficult to film for technical reasons, although movies like The Life of Pi are changing this perception. The impact of CGI technology has had a huge impact on the movie industry and allowed the previously unfilmable to become a reality.

 Sometimes authors are very involved in the process and many may even be the screenwriters. This can actually be a bad thing because they may be too close to the material and find it difficult to adapt. At other times they are not the screenwriters, and there are instances where writers have been very unhappy with the film versions of their work. Roald Dahl and Stephen King are examples of this. Even more extreme was novelist J. D. Salinger who made sure no film versions of his popular novels could ever be made. In this situation, it is clear viewers will not be disappointed.
